$ notify-send "This is some text"
or$zenity --info --text "This is some text"
This will display a text balloon "This is some text".The problem appears when we want to display the output of a command.
For this, I used a python script. Here's the source code:
#!/usr/bin/env python
import os
import sys
import pynotify
pynotify.init("Output comand")
arg=sys.argv[1]
print arg
s = os.popen(arg).read()
n = pynotify.Notification("Output",s)
n.show()
If you wish to use a compound command, then you will need to use quotes.For example, we use the command "ls-a 'as follows:
$python testpy.py "ls -a"
This is just a small example, you can create more complex applications.
